Vivo X300: Vivo X300 is a compact, ultra‑premium flagship that pushes imaging and performance hard, built around MediaTek’s Dimensity 9500, a 200 MP Zeiss‑branded triple camera and a big 6040 mAh battery in a surprisingly small 6.31‑inch body.

It targets buyers who want top‑tier cameras and power but prefer a smaller, easier‑to‑handle phone instead of a huge slab.​

Compact Flagship Design And Display

Vivo X300 uses a 6.31‑inch 1.5K AMOLED panel with a resolution of 1216 × 2640 pixels and around 484 ppi, so text and images look pin‑sharp.

The display supports a 120 Hz refresh rate and high‑frequency 2160 Hz PWM dimming, which keeps scrolling buttery smooth while reducing eye strain in low light.​

The phone remains very pocket‑friendly at roughly 150.6 × 71.9 × 8 mm and just about 190 g, making it noticeably smaller than most 6.7‑inch flagships.

It carries an IP68 rating for dust and water resistance and uses reinforced glass on the front, with multiple colour options like black, blue, red, purple and pink to suit different tastes.​

Dimensity 9500 Power, RAM And Storage

At its heart, Vivo X300 runs on MediaTek’s flagship‑class Dimensity 9500, an octa‑core chip clocked up to about 4.21 GHz and paired with an Arm G1 Ultra GPU.

This platform is designed for demanding workloads like 4K video, console‑level gaming and heavy multitasking, while also enabling advanced AI features in imaging and system optimisation.​

The Indian and global variants offer 12 GB LPDDR5X RAM (with an extra 12 GB virtual RAM option) and 256 GB UFS 4.x storage, with higher trims in some markets going to 16 GB RAM and 512 GB or even 1 TB storage.

There is no microSD card slot, but the fast UFS 4.x storage and large base capacity make it well‑suited for 4K video shooters and app‑heavy users.​

200 MP Zeiss Triple Camera System

On the back, Vivo X300 carries a Zeiss‑branded triple camera: a 200 MP main sensor with OIS, a 50 MP periscope telephoto and a 50 MP ultra‑wide camera.

The main camera uses a large sensor (around 1/1.4–1/1.14 inch class) with a bright aperture, delivering detailed shots, strong dynamic range and reliable low‑light performance with optical stabilisation.​​

The 50 MP periscope telephoto offers around 3x optical zoom and OIS, enabling sharper portraits and distant shots, while the 50 MP ultra‑wide covers landscapes and tight indoor scenes without heavy distortion.

Vivo’s Zeiss optics and coatings, plus colour tuning and tools like 3D LUT import and classic Zeiss portrait bokeh styles, give the X300 a strong edge for creative shooters.​

On the front, a 50 MP selfie camera sits in a punch‑hole and supports 4K and 1080p video, making the phone well‑equipped for creators who vlog or stream.

Both front and rear support up to 4K video recording with advanced stabilisation, letting users capture high‑resolution footage without carrying a separate camera.​​

Battery, Charging And Connectivity

Despite the compact body, Vivo X300 packs a large 6040 mAh battery, giving it more endurance than many rivals with 5000 mAh packs.

It supports 90 W wired fast charging, 40 W wireless charging and reverse charging, so you can quickly top up the phone or use it as a power bank for accessories.​

Connectivity is thoroughly flagship‑grade: dual‑SIM 5G, VoLTE, Wi‑Fi 6 and Wi‑Fi 7, Bluetooth 5.4, NFC, USB‑C 3.2 and an IR blaster for controlling TVs and ACs.

There is an in‑display fingerprint scanner, full GNSS suite including NavIC, and IP68 water resistance, but no 3.5 mm headphone jack or FM radio, which is typical for this class.​

Vivo X300 Software, Pricing And Conclusion

Vivo X300 runs Android 16 with OriginOS 6 on top (in China/selected regions), pairing the Dimensity 9500 with Vivo’s own V‑series imaging chips (like V3+) and VS1 to accelerate camera and display processing.

Software features include advanced night and portrait modes, Zeiss‑style colour profiles, AI scene detection, and a range of performance and battery optimisation tools for gamers and power users.​​

In India, early listings place the X300 around ₹75,999 for the 12 GB + 256 GB model, clearly targeting the premium flagship segment. For buyers who want a compact but extremely capable flagship with a 200 MP Zeiss camera, Dimensity 9500 power, 6040 mAh battery and 90 W charging, Vivo X300 stands out as one of the most complete small‑form‑factor flagships available in late‑2025/2026.
